Specification of Letters Patent.

Application filed January 16.1913. Serial No. 742.424.

To all 'UJ/lllI/L it may concern lie it. known that I. I). lIAm. l t-iuot sox, a I

'itixen ot' the l'nited States. residing at Vernon. in the rountv ol' hhiawassee and Htate ol' .\liehi gan, have invented rertain new and u etul lmprovenu'nts in Measurmgr lustrumeuts ol' whieh the l'ollowilr; ia sperilieation.

.\l v invention relate to improvements in measuring instrmnents and is designed partirularly tor the purpose of measuring and tudieating the quantity of oil r other luhri rant in an oil reservoir.

In the praetieal appliration ol my invention I have specially adapted the devire for use with automobiles to indicate to the driver of the rat the quantity of oil in the oil reservoir, which as I have herein illustrated. is the fly wheel easing located under the ear.

The prime objet't of the invention is to provide an indieator. whieh is eonveniently loeated on the dash hoard ol the automobile in Full view of the driver, and i artuatetl. through the medium ot the oil to indieate the oil level in the reservoir, and thus notify th driver eontinuously. ot the state ot oil in the reservoir.

The invention eonsists in eertain novel features ot eon truetion and eombinations and arrangements of parts as will be hereinat'ter pointed out.

In the accompanying drawings I have illustrated one eomplete example of the physi al embodiment ot my invention eonstruet'ed aeeording to the best mode I have so l'ar devised for the practical application of the principles thereof.

Figure 1 is a side ele 'ation of an engine easing For an automobile, with my appliance adapted thereto. Fig. 2 is a front view of Fig. I as seen From the left, the dash board of the automobile being indieated in dotted lines. Fig. 3 illustrates the deviee, partly in seetion, on an enlarged seale. and connected to the oil reservoir. Fig. I is a faee view of the iudieator plate with its nun-kings, showiug the relation of the indit'ator stem thereto, and an adjusting feature. Fig. 5 is a sec tional detail of Fig. 4, at; right angles thereto.

Tn the n'el'errerl embodiment of my in vention I have illustratedit, in connect-ion with an automobile ot the Ford type of ear,

5 in whit-h the engine easing l is pr vided with a set-tlon or porti n 3 l'orming an oil' re ervoir t rom whieh the eylinders. ete.. are autotmitieally lubrieated in manner well known.

'lhe normal oil level is indit'ated (Fig. :l) in the Il \'\\'llttl easing or oil reservoir 2,

; and by means of the intermediate eonneetit us to he dest'l'ibed. the quantity of oil in the reservoir is imlieated on the intlit'ator plate 3. This plate is lot-ated on the lront dash hoat'd. indirated y the letter in full \iew ol' the driver. and is provided \vith'a normal mark N a maximum marl; I), and a minimum mark I. The plate. is eeured to the dash board by mean ot' screws t. and at its lower end has seem-ed thereto an adjustnu'nt blot-k it. rigidly ti.\'ed to the plate by riwts t3. (3. The perforated blot-k 5 reeeives the upper end of a tu e T. and by means of th et serew 9 in the blot-k. the indit'ator plate may be held rigidly in adjusted post %'i( u with relati n to the tube.

The lower end ol the tu e T l. lixed witlr in the top it of a rup ll. whose bottom 12 is lixed to the eup. 'lhe top it) of the eup is tlt\\'t(l on the eup in order that the Iloat III and its stem l-l may be adapted tor opera ti n with the eup. 'lhe tloat is designed t rest upon the surlat'e ot' the oil eoutained in the eup It, and the stem. whieh is lived to the Ilont. extends upwardly throughthe tube with its end in operative relation to the markings t and I.

The il reservoir and oil rup are e uneeted by a pipe 15. a nipple It' being used to eon 'neet with the cup. and the connection to the reservoir beine made through a box ort-oupling IT l'ormed with a nipple I8 threaded into the reservoir, and having also a drain plug 15 lly uneerewiug the plug- It) the eontents ot' the reservoi and cup may be withdrawn as will readily be understood.

In attaehing the deviee to a ear, the length of the tul and stem is adapted to the height. of the ear and its dash board, and the indieator plate is seeured in adjusted position on the tube by means of the set srrew.

What I elaim isz-- 'Ihe eombinatiou with the oil reservoir ot an automobile of a eonpline box seeured thereto and provided with a drain plus. an il eup and a bent; pipe eonneeting the rap and box, a float in the eup, a tube opening Tn tvslinmny whereof l affix my signature in presem-e of hm witnesses.
